I did try one like that before on a belt drive. I did not like it on the small lawns--- one tire would run off curbs when turning--- one side would hit fences when turning. It would be nice though if you use this on larger lawns. Because we just use the walkbehinds on small lawns,I still like the single wheel velkey.

To answer your question, there rarely used down here mostly by older people with older yazzo mowers, but only for 3-4 acer lawns where its a lot of just going straight. IMO if your mowing normal accounts it wouldnt be very effective it doesn't maneuver well. Hope this helps
